【Abstract】 Parameter measurement for rubber absorbers on crankshafts is necessary in the design, manufacture and maintenance of some internal combustion engine. Sine wave scanning method and pulse excitation method-common methods for the test of rubber absorbers are studied emphatically. Through theoretical analysis and contrast test, the distinguishing features of the two methods are pointed out and a useful reference for the selection and implementation of the test is given.更多还原
